Final Cut Pro to DVD Studio Pro

I've just finished editing my short film with Final Cut Pro and am trying to export it to dvd studio pro. However, when I try to import the final cut pro file in dvd studio pro, it tells me that the format I am trying to import is incorrect.

Is there a way to import a final cut pro file directly into dvd studio pro without compressing it into, say, a quicktime file? If not, in what format do I have to compress it in order to be able to write a dvd and lose as little quality as possible?

I'm basically trying to create a decent dvd version of my film without reducing its quality. Thanks in advance!
